Use Ohm's law, Watt's law, and the power equation to derive formulas for the DC power wheel.

In this animated object, learners observe the changes inside the DC shunt motor that could cause the motor to break apart when its field coil opens. A short quiz completes the activity.

The use of the reciprocal key on the TI-86 scientific calculator is demonstrated in the solution of parallel resistors.

Learners examine a series-parallel circuit and solve 14 problems related to voltage, current, and power. A help screen is provided.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased from 0 Hz towards resonance.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased above resonance.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency increases from 0 Hz toward resonance.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency is increased above resonance.

Learners observe how branch current values in parallel circuits are affected when different values are used. They test their knowledge by answering 11 review questions.
